Sky’s US correspondent Martha Kelner has been reporting from Alaska in the build-up to the summit.
In a green, timber-framed house, she met Meg Leonard – a one-time Republican who describes herself as a “never Trumper”.
On a tree in her front garden, the Ukrainian flag hangs.
She bought it after watching Zelenskyy’s disastrous meeting with Trump in the Oval Office in February on TV.
“I think he was denigrating the president of Ukraine, and that is not good,” she says.
“Right after that, I ordered the flag and hung it up because I support Ukraine. Putin should not be allowed to take land that is not his.
“I think Donald Trump thinks he’s a strongman and that Putin should capitulate to him.
“I don’t think Putin has any intention of doing that.”
Meg says she is appalled that this meeting is taking place one-on-one without Ukraine’s president.
Trump has said that Vlodymyr Zelenskyy will be invited to any follow-up meeting.
“Trump should not be making decisions for Ukraine,” Meg says.
“Zelenskyy should at least have a voice in what is being decided. It is his country and his people.
“Putin’s going to be five miles from here. He’s not welcome by me.
“He is an international criminal; he should be arrested. He is killing women and children, and people in hospitals.”
‘These two guys have the ultimate egos’
But you don’t have to go far in Alaska to find a contrasting view.
In Whittier, a port town mostly home to fishermen, boat operators and tourists, wildlife photographer Tim Colley from New York thinks Trump is an underestimated dealmaker.
He’s not concerned about Zelenskyy’s absence from the summit.
“I think Trump truly wants peace,” Tim tells Kelner. “At some point in time, you’ve got to decide how many more people need to die.
“Does Zelenskyy want to just keep throwing people into the fire?
“I think these two guys [Trump and Putin] have probably the ultimate egos in the world.
“I’m not sure Zelenskyy’s got the self-control to tread lightly on those egos.”
